EmpathyBridge: AI-Powered Voice Emotional Support 🎯

How I Used Murf API

The magic happens with Murf's powerful voice technology:

🎯 Emotion-Aware Voice Selection

The app automatically picks the right voice tone based on your emotional state:

  • Calm support → Cooper's soothing voice
  • Gentle comfort → Hazel's warm tone
  • Crisis support → Deeper, reassuring voices

🚀 Real-Time Voice Generation 

// Instant text-to-speech conversion
const voiceResponse = await murfAPI.generateSpeech({
  text: empathicResponse,
  voice: selectedVoice,
  emotion: detectedEmotion
});
